ULTRA HIGH VACUUM ADHESION AND FRICTION,
Abstract
The problem of determining the magnitude and nature of the forces between grains in a powder was approached by measuring the force between a simple pair of surfaces of known gross contour. This was done in order to minimize the number of parameters which would have to be taken into account in the interpretation of the test results. The test results were evaluated in terms of the characteristics exhibited by the forces involved. The characteristics of particular interest are magnitude, range and dependence on surface cleanliness. These characteristics are used to evaluate which of the various mechanisms which have been proposed to account for adhesion forces is most likely to be dominant. (Author)
